The following topics are dealt with: communication network; communication service; cognitive radio; protocols; security; ad hoc network; mesh network; all optical network; cellular network; network coding; resource allocation; wireless sensor network; and network performance.
As we know, secure communication is the key of success for any wireless network. Denial of Service (DoS) attacks is severe in all the attacks in security of wireless network. Furthermore, cognitive radio networks are vulnerable to DoS attack due to their own characteristics. This paper analyzed the architecture of cognitive radio networks and emphatically discussed the possible various DoS attacks...
The following topics are dealt with : cognitive radio; physical-layer techniques; high-data-rate systems; ad hoc networks; security; energy-aware wireless sensor networks; Web services; user centric network selection; RFID sensor networks; UWB TR receivers; next generation broadband wireless networks; location-based information sharing; and protocols.
Intelligent Transportation system (ITS) using wireless and mobile ad-hoc sensor network has inspired many autonomous applications. Vehicular Ad-hoc network (VANET) is an emerging technology where vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communicate wirelessly using dedicated short-range communication band. In sensor based VANET (S-VANET) issues like response time, data aging, bandwidth,...

Cognitive radio is a promising technology aiming to improve the utilization of the radio electromagnetic spectrum. A cognitive radio device uses general purpose computer processors that run radio applications software to perform signal processing. The use of this software enables the device to sense and understand its environment and actively change its mode of operation based on its observations...
